How do you start xemacs?
From a shell script looking roughly like
#!/bin/bash
no_exit_on_failed_exec=1
exec xemacs -geometry 120x78+0+0

Untested, but kill -SEGV $xemacs_pid should do it.
Yes, and that does leave a coredump. It's strange that I don't get one
for the assertion failure. I'll investigate some more.
Ed> M-x crash-and-dump-core?
That's an interesting concept for a debug build, but we certainly
wouldn't implement that function in a production build. ;-)
I think a better function for me would be M-x assertion-failure, to
specifically test what happens when assert() in the C code returns
false.
